Note: F stands for OFF and N stands for ON status. Network management has higher privilege than
DIP switches except optical module type and ALS function configuration. All configuration
information is available through Hyper Terminal. Bit 1-5 of SW1 are set by default in factory
according to optical module type and other bits are all OFF.
